Well didn't want to sound too facetious but at the end of the day, he/you could explain the situation and in view of the investment in flights, he could end up with tickets to see Arsenal instead!!!
fair enough drew. Point taken and you didn't sound facetious at all.
I'll give the club a bell in the morning - but I imagine the best that they will
do is a refund; can't see them saying "here are four Arsenal tickets" tbh.
